Product Description

The EJ2889-0000 is a CE and UL-certified plug-in module that is specifically designed by Beckhoff for EtherCAT systems. It comes in a compact form of 12 mm x 66 mm x 55 mm that allows for easy installation and efficient organization within control cabinets or systems. The module serves as an interface between automation devices and actuators, isolating electrical signals at the process level. It is designed to utilize ground switching to manage control signals effectively. The module connects the negative side of the circuit to the load, switching the load on or off by completing the circuit through ground. This method ensures precise control over actuators by switching their connection to ground rather than the positive voltage.

The EJ2889-0000 is equipped with 16 outputs. Each output is protected against overload and short circuits, ensuring reliable performance. Users can monitor the state of each channel via LED indicators that provide real-time visual feedback for easier monitoring and diagnostics. The maximum output current for each channel is 0.5 A. It features a breaking energy rating of less than 100 mJ per channel. The low breaking energy helps to minimize the risk of electrical arcing or wear on components over time.

This plug-in module features typical switching times of 50 µs for turning on (TON) and 200 µs for turning off (TOFF). These fast switching times ensure efficient and precise control of connected actuators, allowing quick response in automation tasks. The module provides electrical isolation of 500 V between the E-bus and field potential. This protects the module and connected devices from electrical noise and voltage faults. The unit supports ohmic, inductive, and lamp loads, allowing it to control a wide range of devices.
